So it's an 01 or 02 Super Duty, 8' box, 4x4, 5.4 two valve engine, 4R100 trans, 180k on it. Runs well enough, no mechanical problems other than rear brakes, which will be addressed. What do I need to know about this truck? So far, I've been told to run 5w20 oil due to small oil passages in the engine, and expect 13.mpg. I know the 4 valve engine has a bad reputation. Whhat do I need to do to keep it going?

I have a 2006 supercab with the 4v and had these worries. I bought it used. Ford trained mechanic buddy did the timing chain/cam phaser swap at 150k. Made me swear a blood oath to always use Mobil 1 5/20. He also did the plugs, which are a nightmare if one breaks. Good news is that those long tipped plugs weren't in your 2002. I think you're good mechanically, just pay attention if the motor gets really loud, that's the timing chain about to go. Mine has been plagued with rust, lucky to have a welder-buddy who was able to weld in bed supports, spring brackets, and cab corners. Luckily the rattlecan rusto glossy white is a near perfect white ford paint match. |

The 5.4 either run for 500k miles or they yeet sparkplugs out of their holes. There's not much in between.

You have a 2v, Ford switched to the 3v in the Super Duty in '05 (a year after the F150)
About the only issue with the 2v is blowing spark plugs out and manifold leaks. I've repaired quite a few blown plugs on 5.4s and 6.8s with the helicoil kit and never had another issue on that cylinder when done correctly. Do the SRW trucks have inboard rear brakes? Both my DRWs do but I'm not a full time mechanic anymore and can't remember... I knew a guy with a 6.8 in a 2wd Super Duty that could get 16mpg highway, average was 12-13 for running errands. IMO not terrible- I've got one 6.0 diesel that averages about 13mpg and another that gets single digits (fuel gauge doesn't work and the trip meter is flaky so I just estimate) That's why I drive the Cummins to work now, 18-20mpg is a little easier on the wallet |

Just run whatever oil you're supposed to - 5W30 will be fine or 0w30 if you want to be fancy. change the brake fluid 4r100 - change the fluid, put a radiator sized transmission cooler on it. I think some of them might be able to fit a later model cooler that's huge. |

Yeah common upgrade is to install the radiator cooler from the 6.0 diesel in place of the stock one that came with the gas motor. Just need the cooler and two adapters for the coolant lines |

Quote HistoryOriginally Posted By number40Fan: Make sure the 3rd brake light works. Came to post this. My transmission was over heating when it was -20 degrees out. Changed the fluid multiple times. Put a bigger cooler on etc. Then someone here said check the third brake light. Sure as shit. Now I carry extras. |

Do the plugs and make sure they’ve got anti seize on the threads, trans cooler as mentioned.
ONLY USE GOOD QUALITY FORD BRAKE PRODUCTS ON IT AND MAKE SURE YOUR FRONT U JOINTS ARE GOOD!!!!!! I’d probably still have mine if I did the front end work properly the first time. Don’t use shit calipers from AutoZone or anything. I know they’re all reman but just don’t. It’s actually a great engine. |

Recently got an 03. I like starting fresh on a new vehicle.
I changed all the fluids my self. Engine got 5w-20 Mobil 1, trans got a new filter and full fluid change with Mobil-1 synthetic, transfer case got the same Mobil 1 trans fluid, rear diff got 75-145 Valvoline full syn, front diff got 75-90 full syn, changed the coolant and greased the front end. These trucks are solid. Check all your u joints, belts and inspect for leaks on axles, engine etc. |

The autos seem to get shit fuel economy and the motors are often detuned with the auto in the early 2000s. The V8 gas trucks couldn't hold a candle to the V10 or diesel. |
